Description

Technical Field

[0001] The utility model belongs to the technical field of material hoisting in construction engineering, and specifically relates to a material hoisting and loading device for construction engineering. Background Technique

[0002] The material hoist of the prior art is a device for vertically transporting materials. It drives the cage to move up and down along the guide rail frame through a winch or a traction machine to realize the lifting and lowering of materials. The material hoist usually consists of main components such as a foundation chassis, a guide rail frame, a sky beam, a cage, a winch or a traction machine, and an electrical operation control cabinet.

[0003] In the use of construction engineering, the hoisting equipment is usually installed and fixed at the corresponding position in advance. The materials to be transported are put into the cage, and then the cage is lifted by the winch, so that the materials are moved to the corresponding height, and the materials are disassembled to realize the operation of loading and hoisting the materials;

[0004] However, in the actual use process, due to the possible overweight of the materials in construction engineering, when loading, weighing equipment (such as an electronic scale, a weighbridge, etc.) needs to be used to weigh the materials to ensure that their weight does not exceed the maximum load-bearing capacity of the cage. If there is no weighing equipment, the operator can estimate the approximate weight of the materials according to experience and compare it with the maximum load-bearing capacity of the cage. This method is very labor-intensive, and the manual estimation is not accurate enough. Once overloaded, it will cause great harm to the cage, and may lead to problems such as cage structure damage, component fatigue, and control system failure. In severe cases, it may even cause safety accidents such as cage falling.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

Detailed implementation manners

[0028] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0029] Please refer to Figures 1-4 As shown, in this embodiment, a building engineering material hoisting and loading device is provided, which includes a chassis 1. A guide rail frame 2 is fixedly connected to the upper side of the chassis 1. A winch 3 is fixedly connected to the upper side of the chassis 1 and on one side of the guide rail frame 2. A cage 4 is slidably fitted on one side of the guide rail frame 2. A lifting steel wire 5 that cooperates with the winch 3 and the guide rail frame 2 is arranged on the upper side of the cage 4.

[0030] On the lower side of the inner wall of the cage 4, an alarm bin 6 is opened. On the lower side of the inner wall of the alarm bin 6, a plurality of load-bearing springs 7 are fixedly connected. On the upper sides of the plurality of load-bearing springs 7, a lower pressing plate 8 is fixedly connected. On the lower side of the lower pressing plate 8, a trigger rod 10 is fixedly connected. An alarm assembly 11 that cooperates with the trigger rod 10 is arranged on the lower side of the inner wall of the alarm bin 6. A limiting mechanism 12 is arranged on the upper side of the cage 4. A closing assembly 13 is arranged on one side of the cage 4.

[0031] Please refer to Figure 1 and Figure 4 , the alarm assembly 11 includes a push switch 111 fixedly connected to the lower side of the inner wall of the alarm bin 6, an installation opening 112 opened on one side of the inner wall of the alarm bin 6, and an alarm 113 fixedly connected to the inner wall of the installation opening 112 and cooperating with the push switch 111. Through the electrical connection between the alarm 113 and the push switch 111, when the push switch 111 is squeezed and opened, the alarm 113 emits an alarm sound for reminding to use it in a standardized manner.

[0032] Please refer to Figure 4 , the limiting mechanism 12 includes two guide grooves 121 fixedly connected to the upper side of the inner wall of the cage 4, a threaded rod 122 rotatably fitted on one side of the inner walls of the two guide grooves 121, two tightening plates 123 threadedly fitted on the threaded rod 122, and a driving motor 124 fixedly connected to both sides of the cage 4 and cooperating with the two threaded rods 122. By starting the driving motor 124 to drive the threaded rod 122 to rotate, the tightening plates 123 move in the guide grooves 121 to tighten both sides of the materials inside the cage 4 to fix them, improving the stability of hoisting.

[0033] Please refer to Figure 1 and Figure 2, the closing component 13 includes two convex grooves 131 opened on the upper side of the cage 4, convex blocks 132 slidably fitted on the inner walls of the two convex grooves 131, a sealing plate 133 fixedly connected to one side of the two convex blocks 132, a stepping motor 134 fixedly connected to the upper side of the cage 4, a lifting lead screw 135 fixedly connected to the output end of the stepping motor 134, and a force-receiving block 136 fixedly connected to one side of the sealing plate 133 and threadedly engaged with the lifting lead screw 135. By driving the lifting lead screw 135 to rotate through the stepping motor 134, the force-receiving block 136 is moved, so as to realize the up-and-down movement of the sealing plate 133 to seal or open the cage 4. When the sealing plate 133 moves up and down, the convex blocks 132 slide in the convex grooves 131 to realize the limit.

[0034] Please refer to Figure 4 , a plurality of hollow cylinders 14 are fixedly connected to the upper side of the inner wall of the alarm bin 6. A limiting rod 15 fixedly connected to the lower pressing plate 8 is slidably fitted on the inner walls of the plurality of hollow cylinders 14. When the lower pressing plate 8 moves up and down, its limiting rod 15 will slide correspondingly in the hollow cylinders 14 to guide the lower pressing plate 8.

[0035] Please refer to Figure 3 and Figure 4 , a hollow load-bearing ring 16 is fixedly connected to the upper side of the inner wall of the alarm bin 6. The hollow load-bearing ring 16 is arranged outside the pressing switch 111. When the hollow load-bearing ring 16 is outside the pressing switch 111, it can protect the pressing switch 111. When the lower pressing plate 8 drives the trigger rod 10 to move downwards and contacts the hollow load-bearing ring 16, the hollow load-bearing ring 16 will support the trigger rod 10 and will not cause damage to the pressing switch 111.

[0036] Please refer to Figure 2 and Figure 3 , a hidden groove 17 is opened on the upper side of the chassis 1 and below the cage 4. A buffer pad 18 is fixedly connected to the inner wall of the hidden groove 17. When the cage 4 moves downwards, the buffer pad 18 can buffer the impact force at the moment when the cage 4 contacts the chassis 1 in the hidden groove 17.

[0037] The implementation principle of an embodiment of a building engineering material lifting and loading device in this application is as follows: When in use, first install the chassis 1 at the corresponding position. When in use, put the materials into the cage 4 and above the lower pressing plate 8. By starting the winch 3 to lift the lifting wire 5, the cage 4 is lifted upwards. The cage 4 slides on the guide rail frame 2 and has a limiting function at the same time, realizing the loading and lifting of the materials.

[0038] When placing materials, after the materials are placed on the lower pressing plate 8, the pressure generated will squeeze the lower pressing plate 8 and the load-bearing spring 7. The load-bearing spring 7 has a certain pre-set pressure, and its pre-set can match the weight it bears. When the load-bearing spring 7 is contracted to a corresponding degree, the lower pressing plate 8 will squeeze the pressing switch 111, and then transmit a signal to the alarm 113 in the mounting port 112 through the pressing switch 111, causing the alarm 113 to alarm and reminding the operator to stop loading, so as to avoid structural damage, equipment failure and even safety accidents caused by overloading, thus improving the convenience during use;

[0039] After installation, the driving motor 124 can be started respectively to drive the guide groove 121 to rotate, so that the two tightening plates 123 tighten the two sides of the placed materials, avoiding the situation of displacement caused by stacking of materials during transportation, making the cage more stable during lifting, reducing shaking and swinging, and being more conducive to the smooth operation of the cage.

[0040] The present utility model is not limited to the above embodiments. Any person should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model.
